# Decisions
|
||||
|
||||
## 2026-04-24 – Audit LOW fixes: stdout null, utf-8 path, debug value, hidden sessions (v0.8.6)
|
||||
|
||||
- **Who**: ClaudeCode, Dom
|
||||
- **Why**: Four LOW findings cleared in a single pass. (1) `power::run_command` piped stdout it never read — structurally fragile even though current callers stay well under the pipe buffer. (2) Relative wallpaper paths were resolved via `to_string_lossy`, silently substituting `U+FFFD` for non-UTF-8 bytes and producing a path that cannot be opened. (3) `MOONGREET_DEBUG` escalated log verbosity on mere presence, so an empty variable leaked auth metadata into the journal. (4) `Hidden=true` and `NoDisplay=true` `.desktop` entries appeared in the session dropdown even though they mark disabled or stub sessions.
|
||||
- **Tradeoffs**: Gating debug on the literal value `"1"` is slightly stricter than most tools but matches the security-first posture. Filtering Hidden/NoDisplay means legitimately hidden but functional sessions are now unselectable from the greeter — acceptable, that is the convention these keys signal.
|
||||
- **How**: (1) `.stdout(Stdio::null())` replaces the unused pipe. (2) `to_string_lossy().to_string()` replaced by `to_str().map(|s| s.to_string())` with a `log::warn!` fallback for non-UTF-8 paths. (3) `match std::env::var("MOONGREET_DEBUG").ok().as_deref()` → `Some("1")` selects Debug, everything else Info. (4) `parse_desktop_file` reads `Hidden=` and `NoDisplay=`, returns `None` if either is `true`.
|
||||
|
||||
## 2026-04-24 – Audit MEDIUM fixes: FP double-init, async avatar, symlink, FD leak (v0.8.5)
|
||||
|
||||
- **Who**: ClaudeCode, Dom
|
||||
- **Why**: Six MEDIUM findings: (1) i18n test `all_string_fields_nonempty` missed four string fields — future locales could ship empty strings unnoticed. (2) Fast user-switch could spawn two parallel fprintd `init_async` calls because both coroutines saw `fingerprint_probe = None` before either stored its probe. (3) Synchronous avatar decode via `Pixbuf::from_file_at_scale` on the GTK main thread, stalling clicks. (4) Wallpaper `MAX_WALLPAPER_FILE_SIZE = 50 MB` bounded decode at up to ~2 s. (5) Fallback wallpaper path used `is_file()` which follows symlinks, inconsistent with the symlink-rejecting user-config path. (6) After a failed login the cloned `greetd_sock` descriptor remained in shared state until the next user switch, accumulating stale FDs across retries.
|
||||
- **Tradeoffs**: The init-race guard uses a bool flag on `GreeterState` + a 25 ms polling yield — cheap and race-free, but introduces a very short latency when a second probe waits. Lowering `MAX_WALLPAPER_FILE_SIZE` to 10 MB and `MAX_AVATAR_FILE_SIZE` to 5 MB caps worst-case decode but rejects legitimately huge (4K raw) wallpapers; acceptable for a greeter. Async avatar decode shows the default icon for a frame or two on cache miss.
|
||||
- **How**: (1) Four new `assert!` lines in `i18n::tests::all_string_fields_nonempty`. (2) New `fingerprint_probe_initializing: bool` on `GreeterState`, atomic check-and-set under `borrow_mut`, losing coroutines yield via `glib::timeout_future` until the winning init completes. (3) `set_avatar_from_file` uses `gio::File::read_future` + `Pixbuf::from_stream_at_scale_future` inside a `glib::spawn_future_local`, sets the default icon first, swaps on success. (4) Lower both size constants. (5) `resolve_background_path_with` now applies the same `symlink_metadata` + `!is_symlink` check to the Moonarch fallback. (6) After the login worker returns, `state.greetd_sock.lock().take()` drops the stale clone regardless of login outcome.
|
||||
|
||||
## 2026-04-24 – Audit fix: shrink password-in-memory window (v0.8.4)
|
||||
|
||||
- **Who**: ClaudeCode, Dom
|
||||
- **Why**: Security audit flagged the GTK password path as holding more copies of the plaintext password in memory than necessary. `attempt_login` wrapped the already-`Zeroizing<String>` caller value into a second `Zeroizing<String>` (`password.to_string()`), and the GTK `GString` backing `entry.text()` persisted in libc malloc'd memory until the allocator reused the page.
|
||||
- **Tradeoffs**: The GTK `GString` and the libc `strdup` copy on the PAM FFI boundary remain non-zeroizable — this is an inherent GTK/libc limitation, already documented in CLAUDE.md. This change reduces the Rust-owned copies to one and clears the `PasswordEntry` text field immediately after extraction to shorten the GTK-side window.
|
||||
- **How**: (1) `attempt_login` now takes `password: Zeroizing<String>` by value instead of `&str`, moving ownership into the `spawn_blocking` closure. (2) The redundant `Zeroizing::new(password.to_string())` inside `attempt_login` is removed. (3) `password_entry.set_text("")` is called right after the password is extracted from the activate handler, shortening the lifetime of the GTK-internal buffer.
|
||||
|
||||
## 2026-04-21 – Ship polkit rule in moongreet instead of moonarch (v0.8.3)
|
||||
|
||||
- **Who**: ClaudeCode, Dom
|
||||
- **Why**: Reboot/shutdown from the greeter silently failed on a fresh install. The polkit rule that grants the `greeter` user `org.freedesktop.login1.{reboot,power-off}` lived in the moonarch repo but was never installed by any PKGBUILD. The laptop worked only because the rule had been hand-deployed once.
|
||||
- **Tradeoffs**: Rule ownership moves from moonarch (system defaults) to moongreet (greeter-specific auth). Cleaner boundary — moonarch no longer needs to know about the greeter's auth requirements — but it means moongreet is now responsible for a system polkit rule that ties it to a fixed username (`greeter`).
|
||||
- **How**: Source file moved to `moongreet/config/polkit/50-moongreet-power.rules`, installed to `/etc/polkit-1/rules.d/` by `moongreet-git/PKGBUILD`. Old file removed from the moonarch repo.
|
||||
|
||||
## 2026-04-09 – Monitor hotplug via ListModel items-changed
|
||||
|
||||
- **Who**: ClaudeCode, Dom
|
||||
- **Why**: Greeter windows were only created at startup. If a monitor was hotplugged (e.g. HDMI reconnect), it would show no greeter UI. Aligned with moonlock's hotplug fix (same day).
|
||||
- **Tradeoffs**: Hotplugged monitors get greeter windows without keyboard input (keyboard stays on the primary monitor). Acceptable — user can still interact on the primary screen.
|
||||
- **How**: Connect to `display.monitors().connect_items_changed()` and create new greeter windows for added monitors. Shared state (config, texture, blur_cache) moved to Rc for the closure.
|
||||
|
||||

## 2026-03-28 – Remove embedded wallpaper from binary
|
||||
|
||||
- **Who**: ClaudeCode, Dom
|
||||
- **Who**: Selene, Dom
|
||||
- **Why**: Wallpaper is installed by moonarch to /usr/share/moonarch/wallpaper.jpg. Embedding a 374K JPEG in the binary is redundant. GTK background color (Catppuccin Mocha base) is a clean fallback.
|
||||
- **Tradeoffs**: Without moonarch installed AND without config, greeter shows plain dark background instead of wallpaper. Acceptable — that's the expected minimal state.
|
||||
- **How**: Remove wallpaper.jpg from GResources, return None from resolve_background_path when no file found, skip wallpaper window creation and background picture when no path available.

## 2026-03-28 – Optional background blur via `image` crate (superseded)
|
||||
|
||||
- **Who**: ClaudeCode, Dom
|
||||
- **Who**: Selene, Dom
|
||||
- **Why**: Blurred wallpaper as greeter background is a common UX pattern for login screens
|
||||
- **Tradeoffs**: Adds `image` crate dependency (~15 transitive crates); CPU-side Gaussian blur at load time adds startup latency proportional to image size and sigma. Acceptable because blur runs once and the texture is shared across monitors.
|
||||
- **How**: `load_background_texture(bg_path, blur_radius)` loads texture, optionally applies `imageops::blur()`, returns blurred `gdk::Texture`. Config option `background-blur: Option<f32>` in `[appearance]` TOML section.
|
||||
|
||||
## 2026-03-28 – Audit fixes for shared wallpaper texture (v0.4.1)
|
||||
- **Who**: ClaudeCode, Dominik
|
||||
- **Who**: Selene, Dominik
|
||||
- **Why**: Quality, performance, and security audits flagged issues in `load_background_texture()`, debug logging, and greetd error handling
|
||||
- **Tradeoffs**: GResource path now requires UTF-8 (returns `None` for non-UTF-8 instead of aborting); 50 MB wallpaper limit is generous but prevents OOM; debug logging off by default trades observability for security
|
||||
- **How**: GResource branch via `resources_lookup_data()` + `from_bytes()` (no abort), file size limit, error details only at debug level, `MOONGREET_DEBUG` env var for log level, greetd retry path truncation matching `show_greetd_error()`
